2G Having issues with idle

Had problems with it dying after warm up. Adjusted the idle screw, sprayed some sea foam in. Had it idling fine for 5 minutes then it started to rev to 3k. Dirty throttle body or something else?

I assume you are talking about the wire for the 1g IPS. That's a 1g thing. The 2g TPS has the IPS (Idle switch) internally. So if your car is 2g with 2g harness, then you wouldn't need to wire the 1g IPS. The Yellow/Red wire in the video you upload above is the one for the 2g IPS. But you would still need the 1g IPS physically (or something instead of that) to set the throttle plate full closed position.

Thanks man I already found one in my area going to be doing burnouts as soon as I get it I was wondering why I couldn’t get the stuff right I couldn’t find it and I thought it was a 2 g throttle body

What I know about this car anything that a 1 g has that can be swapped to a 2 g is swapped.

purge vale deleted charcoal can deleted 6 bolt 16g turbo e prom ecu arp head studs the biggest bolt ons that fit are on. 3port boost controller and afr gauge

I don’t know if it has Dsm link or not but it has been what I was told is flash tuned as of what is currently running in it by the engine builder and the dude I bought the car from I will probably open the ecu next after I get the ips

The only thing that I can’t get working electronically is the dummy light and oil pressure gauge in the dash I’m guessing it’s just Burt out because everything else works and I checked many different pictures on the forms and got confirmation from a dsm builder in my area that it’s wired correctly as well on the forms

The part number 07702 is what the 4 pin replaces is what I’m asking? I have asked the Dsm people around my city but I will probably be making one myself if the wire isn’t necessary for my setup

That's what I meant above. You don't have it and you won't need it. That's the same as below.

Great. Should start from properly adjust the throttle body (TPS, BISS, Throttle plate position, Cable) and fix all vacuum/boost leak. Then we will see if you would still have unstable idle, or not.

Will be doing it soon and will update
I found how to adjust it with a voltmeter to .48-.52 volts at idle if I’m reading the manual correctly

You might find the voltage fluctuates depending on if the engine is running or not. It makes it fun to get the value you want.

Steve’s first post is for a 1g tps. You said you have a 2g tps. I don’t get hung up on the voltage as long as it’s close.

Set setting the IPS for the TPS is critical for a smooth idle and off throttle cruising unless you’re lazy just use the adjustment in ecmlink which I don’t remember if you have or not.

Which leads me back to my first post. When you said you adjusted the idle screw. Did you adjust the biss or the sas?

If you moved the sas you need to set it back to the factory setting before adjusting the tps or your shooting yourself in the foot.

My previous tps struggles may help you but you’ll need the sas first

Yes I was I understand what I have to do I believe

ACC on throttle set screw with 0.177 gauge at the screw stop

Turn the tps fully counter clockwise

Turn the tps clock wise with a voltage meter on pin 3 and 4 do untill it hits 0

Tighten the bolts
.45 at idle 4.95 volts at full throttle


Then check when at idle that it’s getting 0.65 volts

Then I’m able to adjust my ips and biss

I set it by hand and got it to idle perfectly for about 10 minutes I need to now properly set the tps

Also I turned up timing by 1 degrees and it helped a lot

I have since ordered a throttle position screw and a throttle position sensor will post another update when I receive them in the mail
